This U.S. 1 Improvement Project focuses on the replacement of aging bridges and highway safety enhancements of an approximate four-mile segment of the U.S. 1 Expressway known as the Lincoln Highway. Situated in Bucks County, the project extends from just north of the City of Philadelphia at Old Lincoln Highway in Bensalem Township to just north of the PA 413 (Pine Street) overpass in Middletown Township and Langhorne Borough.
The project traverses four municipalities: Bensalem and Middletown Townships, Langhorne Borough, and Langhorne Manor Borough. This suburban regional arterial/limited-access freeway is a corridor providing access to residential communities and commercial and industrial developments. The overall U.S. 1 Improvement Project was sub-divided by PennDOT into three sub-projects to allow the progressive delivery of successive smaller projects.
